Interesting, wonder if this will happen in Cali now that weed is legal. Any long term users want to chime in?
On a recent shift in the ER, after multiple rounds of medicine to control his nausea, vomiting and abdominal pain, a patient explained to me that he had been smoking marijuana daily over the past 5-10 years. He also stated that he would often take hot showers and baths to help control his symptoms.
At this point--after describing how hot showers relieved his symptoms--it was clear to me that he was suffering from a poorly understood condition that some long-term heavy pot smokers experience, now known as cannabinoid hyperemesis syndrome, or CHS.
LaPook interviewed Dr. Kennon Heard, who described his 2015 study from the the journal Academic Emergency Medicine, which noted that, after medical marijuana was legalized in 2009, the prevalence of cyclical vomiting visits associated with cannabis doubled in two Colorado hospitals. Colorado made recreational marijuana legal in 2012.
chronic marijuana use stimulates cannabinoid receptor type 1 (CB1) in the brain, which results in reduced contraction of smooth muscle in the wall of the intestines. Researchers believe that because CB1 is situated closer to the so-called thermoregulatory center in the hypothalamus, the continuous hypothalamic stimulation of CB1 might be relieved by showering with hot water. Another theory involves the concept known as “cutaneous steal syndrome” in which hot showers help ease symptoms by drawing blood flow away from the gut, since chronic cannabinoid use results in CB1-induced vasodilation.

NEW YORK -- For more than two years, Lance Crowder was having severe abdominal pain and vomiting, and no local doctor could figure out why. Finally, an emergency room physician in Indianapolis had an idea.
“The first question he asked was if I was taking hot showers to find relief. When he asked me that question, I basically fell into tears because I knew he had an answer,” Crowder said.
The answer was cannabinoid hyperemesis syndrome, or CHS. It’s caused by heavy, long-term use of various forms of marijuana. For unclear reasons, the nausea and vomiting are relieved by hot showers or baths.

Primary Outcome
In the pre- and postliberalization periods, there were 41 versus 87 visits for cyclic vomiting, respectively (Figure 1). Thus, the prevalence for cyclic vomiting visits increased from 41 per 113,262 ED visits to 87 per 125,095 ED visits after liberalization, corresponding to a prevalence ratio of 1.92 (95% CI = 1.33 to 2.79).
